TWO-NEEDLE SEWING-MACHINE AND GUIDE THEREFOR.

SPECIFICATION forming part of Letters Patent No. 419,584, dated January14, 1890.

Application filed April 2, 1889.

To all whom it may concern:

Be it known that I, ABRAHAM L. OooMBs, of Lynn, county of Essex, Stateof Massachusetts, have invented an Improvement in Sewing=Machines, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters and figures on the drawingsrepresenting like parts. I

This invention relates to improvements in sewing-machines, and has forits object to provide a two-needle machine having an ordinarypresser-foot-as, for instance, a roller presser-footwith an additionalpresser-foot adapted to serve as a guide for the needles to prevent themcoming in contact with each Other.

My invention consists in the combination, with a presser-foot of asewing-machine having two closely-adjacent needles, of an independentvertically-movable needle-guide foot having two guide-eyes for saidneedles, as hereinafter more fully described, and as indicated by theclaims hereunto appended.

Figure 1 shows in elevation the needle-bar, presser-bar, and independentfoot or needleguide and operating parts embodying this invention, theneedle-bar and guide for the needles being in their uppermost position;Fig. 2, a similar View to Fig. 1, the needlebar and guide for theneedles being in the lowermost position; Fig. 3, a side view of theparts shown in Fig. 2, and Fig. 4 details of the independent foot orguide for the needles to be referred to.

The frame or arm a of the machine, the needle-bar I), having twoclosely-adjacent needles 2, the presser-bar 0, (herein shown as having aroller presser-foot,) and means for lifting the said presser-bar are allof usual construction. An independent needle-guide bar at has itshearings in the arm or head a to move parallel with the needle-bar b,and its foot (1 is normally held down upon or near to the work by meansof a spring (1', which is interposed between the bearing projection ofthe arm and the collar, shoulder, or projection (1 secured to or formedupon Serial No. 305,651. (No model.)

- A collar or should er I) is secured to or formed upon the needle-barb, which, as the latter rises and falls, strikes the under side of thecollar or projection d and raises the bar d, and as the said needle-barb falls the spring d causes the bar cl to fall. The two oppositepositions of the needle-bar and the relative positions of the guide-bard may be seen in Figs. 1 and 2. By this foot it will be seen that thetwo needles remain continually in the guide-eyes thereof, so that thereis no chance of fouling.

I do not desire to limit myinvention tothe means herein shown for movingthe needleguide bar or foot, as it is obvious that it may be moved invarious ways.

I- claim .1. In a sewing-machine, the combination, with apresser-bar anda foot or presser, of a needle-bar having two closely-adjacenteyepointed needles, andan independent vertically-movable needle-guidebar provided with a needle-guide foot arranged adjacent to said foot orpresser and having two eyes for said needles, substantially as setforth.

2. In a sewing-machine, the combination, with a presser-bar and foot orpresser, of a needle-bar having two closely-adjacent eyepointed needles,an independent verticallymovable needle-guide bar provided with aneedle-guide foot arranged to bear on the work adjacent to said foot orpresser and having two guide-eyes for said needles, and means forraising and lowering said needleguide foot, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ABRAHAM L. COOMBS.
